White Fly

Whitefly

Whitefly can explode quickly, so the only sure control is to prevent buildup. In greenhouses remove host plant material and infested lower leaves of plants and destroy all plant prunings.

Once you have a problem, reduce populations with hot water, neem oil or with yellow sticky banners

An inoculative early release of Delphastus in whitefly hot spots can be cost-effective in combination with regular releases of parasitoids. While green lacewing will eat parasitized whitefly scale, they can control whitefly with weekly releases of one larva every fourth plant if the canopy is touching.
